Hideo Kojima has told fans that he's "sick and tired" of people asking whether the newly-unveiled Ground Zeroes is in fact the mysterious Project Ogre (spoiler alert: it isn't). Interestingly, though, a new report also suggests that the open-world project is not Metal Gear Solid 5 either... perhaps making it a prologue to the next numerical entry in the series.
First to what we know: Hideo Kojima is getting bored of people asking him about Project Ogre. "While I am happy to know people liked “MGS Ground Zeroes”, I’m sick & tired of people keep asking me like “is that project Ogre?” here in Seattle everyday," he tweeted. "Project Ogre is what the project that Ogre appears. Ogre does not appear in “MGS Ground Zeroes” trailer.”
So that's that... but here's where things get slightly more interesting. CVG has apparently heard that Project Ogre is in fact the codename for Metal Gear Solid 5 - heavily suggesting, therefore, that another numerical sequel is still in the offing. It's likely that Ground Zeroes will act as a weighty introduction or prologue, though personally we're not entirely convinced that MGS 5 and Project Ogre are necessarily one and the same. As always, watch this space.
